IMUを用いて日常生活環境下で計測された運動からの転倒リスク指標の抽出

抄録

Fall risk assessments in a home are important to co-medical staff when patients discharge from a hospital. The purpose of this research is to propose a simple and easy way of measuring and visualizing the fall risk. As the first step, we collected motion data using an IMU sensor suit and a foot sensor. We showed the time point when the margin of stability (MoS) of the participant is less than 5 cm. Experiments are conducted under conditions in which a participant moves putting an age simulation suit or as usual in a living lab / in a vacation rental. Results showed the usability of this system in the point of enabling us to compare the risky place at home visually.
